Iran-backed Houthis enter the monthlong war and could further threaten global shipping

Iranian-backed Houthi rebels have entered the monthlong war in the Middle East and claimed they launched missiles toward Israel. The Houthis could threaten another important global shipping lane in the region. About 2,500 U.S. Marines have arrived in the Middle East to strengthen the largest U.S. military buildup in the region in more than two decades.
